kdu_roi_image

This abstract base class is not derived by any class defined by the Kakadu core system. To use ROI features, the application must supply a suitable derivation. Some useful examples are provided with the "kdu_compress" application. The derived object might obtain ROI information interactively from a user (e.g., in a clinical application).

However the ROI information is obtained, the derived object must be able to supply a suitably derived kdu_roi_node object, which is capable of delivering the ROI information for any given image component and any given tile region. The present base class only defines the formal mechanisms to be used to accessing these derived kdu_roi_node objects.
